The empirical correlation developed in a previous paper is extended to hydrogen bonding and quantum pure compounds. The calculations of the second virial coefficients only require additional parameters, the reduced dipole moment for the associated compounds (alcohols, amines, water) and reduced de Broglie wavelength for the quantum compounds (H-2, D-2, T-2, He-3, He, Ne). The results agree well with experimental data. (c) 2007 Elsevier B.V. All rights reserved.
